Description

Hilfsvorrichtung für die Herstellung hohler Zahnkronen aus Metallguß. Die Erfindung betrifft eine Hilfsvorrichtung für die Herstellung hohler Zahnkronen aus Metallguß. Die bisher allgemein übliche Art der Herstellung von (hohlen) Goldkronen bestand in der Benutzung von sogenannten Kronenzieh- oder Stanzapparaten. Seitdem das Gußverfahren in die Zahntechnik eingeführt worden ist, war man bestrebt, ein Verfahren zu finden, welches die Herstellung von Goldkronen mittels des Gußverfahrens ermöglichte. Alle bisher angewandten Methoden haben sich aber als unvollkommen und zu zeitraubend erwiesen.Auxiliary device for the production of hollow tooth crowns from cast metal. The invention relates to an auxiliary device for the production of hollow tooth crowns made of cast metal. The previously common way of manufacturing (hollow) gold crowns consisted in the use of so-called crown pulling or punching devices. Since the casting process has been introduced into dental technology, efforts were made to create a To find a method, which the production of gold crowns by means of the casting process made possible. All methods used so far have proven to be imperfect and Proven to be too time consuming.

Die Erfindung ermöglicht es nun jedem Fachmann, in kürzester Zeit eine Krone zu gießen, die allen Anforderungen entspricht.The invention now makes it possible for any person skilled in the art, in a very short time to cast a crown that meets all requirements.

Die Erfindung besteht in einem aus Stahl oder anderem Material hergestellten Zahnkronenleisten in Form eines Stabes, welcher, wie aus der Zeichnung ersichtlich, der Länge nach in drei oder mehrere Teile zerlegbar ist. Das eine Ende dieses Stabes hat die Form eines menschlichen Zahnes, während das andere Ende als glatter Schaft ausgebildet ist. Die einzelnen Teile des Kronenleistens sind an ihren Berührungsflächen genau aufeinandergeschliffen und werden durch einen Verschluß in richtiger Lage zusammengehalten.The invention consists in one made of steel or other material Tooth crown strips in the form of a rod, which, as can be seen from the drawing, can be dismantled lengthwise into three or more parts. One end of that staff has the shape of a human tooth, while the other end is a smooth shaft is trained. The individual parts of the crown molding are at their contact surfaces sanded exactly on each other and are in the correct position by a lock held together.

Der Herstellungsgang einer Krone mittels des Kronenleistens ist kurz folgender: Das leicht eingefettete Xronenende des Leistens wird in flüssiges Wachs getaucht, so daß es sich mit einer dünnen Wachsschicht überzieht. Das Entfernen dieses Wachsmodells vom Leisten geschieht nun dadurch, daß der Verschluß, welcher die einzelnen Teile des Leistens zusammenhält, abgenommen wird, worauf die einzelnen Teile, und zwar erst der mittlere, aus dem Wachsmodell herausgezogen werden. Das somit erhaltene Wachsmodell wird nach dem üblichen Verfahren eingebettet und gegossen. Die mittels der Kronenleisten hergestellten Kronen haben eine genaue anatomische Form und besitzen keine Naht und Lötestelle. Ein weiterer Vorteil besteht darin, daß man Stellen, die besonders verstärkt sein sollen oder besondere Bildung der Kaufläche, des Zahnrückens, der Zahnschneide usw. haben sollen, durch entsprechendes Modellieren und Auftragen von Wachs am Modell ändern kann, bevor es vom Leisten abgenommen wird. Die Zahnkronenleisten werden für jede Zahnart des menschlichen Gebisses (für untere und obere Schneide-, Eck- und Backenzähne) hergestellt.The manufacturing process of a crown using the crown molding is short the following: The lightly greased Xronenende of the last is in liquid wax dipped so that it is covered with a thin layer of wax. The removal This wax model of the last is now done by the closure, which holds the individual parts of the last together, is removed, whereupon the individual Parts, and only the middle one, can be pulled out of the wax model. That The wax model thus obtained is embedded and cast according to the usual method. The crowns made by means of the crown ridges have a precise anatomical shape Shape and have no seam or soldering point. Another advantage is that one places that should be particularly strengthened or special education of the Chewing surface, the back of the tooth, the tooth cutting edge, etc. should have by corresponding Modeling and applying wax on the model can change before it is off the last is removed. The dental crown strips are made for every type of human tooth Set of teeth (for lower and upper incisors, canines and molars).
